Answer:
Arsenic, As, has atomic number 33, which is the number of protons in the nuclei of its atoms. A neutral As atom would also have 33 electrons. The electron configuration of a neutral arsenic atom is [Ar]3d104s24p3
Explanation:
To calculate the atomic mass<span> of a single </span>atom<span>, add up the </span>mass<span> of protons and neutrons.
So, your answer would be A) add the number of protons and neutrons</span>
An endothermic process is a process that needs energy in order to proceed. This is the opposite of exothermic which is a process of releasing energy. During an endothermic process, the temperature of the system is increased thus exciting the molecules and allowing them to move faster. This will cause liquid to vaporize.
Answer: 500g
Explanation:
We are asked to find the theoretical yield of a reaction, and we are given the following information:
In order to find the the theoretical yield we must use the following formula:
We have to convert the percents to real numbers before the calculations. We can do it dividing the percent value into 100, so:
